You need to re-pack the ROM with a working Arm7 file, after you have done this the game works fine on R4.
* Download DSLAZY, open up the GTA Rom
* nds unpack the ROM, a folder will open up,
* Copy accross and override the arm7 and arm9 file. Do not close DSLAZY
* In DSLAZY do a nds repack, saving the nds file with a new name
* Copy to R4 and enjoy
Much kudos to fatcowball for the files
Tested using R4 v.1.18
